(Cl. 101-93) This invention relates to an improvement in the measuring bar inits rearmost position and interpreting and printing devices, which is parwith the stop restoring actuating member and ticularly adapted to the alphabetic interpreter sensing mechanism in section, in their properre plates as used in the Printing interpreter, dislationship with said plate.

As viewed 55 in Fig. 3, the 12 stop has an upwardly extending projection 20, which underlies rockable measuring element 30. Consequently, when said 12 stop is elevated the forward end of element 80 will be raised to a position above the highest point of any of the remaining eleven stops 1 which might be raised and the forward end of measuring element 4 will then abut against the raised stop.

As may be seen in Fig. 3, the raising of the forward end of member will allow the measuring unit 4 to move forwardly an extra distance, thereby positioning a different character on typewheel l9. By interspersing the letters of the last half of the alphabet between the letters of the first half on type-wheel E9, the above described extra movement of measuring unit 4 will enable the printing of the entire alphabet from a 12 hole position card.

The reason for locking up interponents I7 is: the card must travel to a second or printing position where printing occurs. The invention includes the incorporation of a printing interpreter plate, as disclosed in the above cited British patent, with a bent hook member I, one end of which is pivoted to a stop restoring bell crank 2 and the other end of which is bent over to be operable upon a rockable measuring element 3 pivoted to reciprocating measuring memher 4. The bent over end of hook member I is slotted to engage a grooved stud 5, to maintain alignment of said member I. The long arm of bell crank I2 (as shown in the above cited British patent) is shortened, in the present invention, to remove nearly all downward spring pressure from the rockable measuring element 3. The bell crank 2 is actuated once during each cycle of the printing interpreting machine by a cam operated universal bail 6, to restore any of the stops 1 which may have been elevated by the sensing mechanism. The rocking of bail 6 occurs at a time in the cycle just after the latching mechanism has been unlatched. As stated above, the hook member I is pivoted to bell crank 2, consequently, whenever said bell crank 2 is actuated, the rockable measuring element 3 will be positively drawn downwardly to its normal position.

A second embodiment of this invention is shown in Fig. 3. In this second embodiment the means for returning the rockable measuring element includes a spring actuated toggle-link mechanism which is disabled during sensing by the engagement of a stud, mounted on the interpreter plate, with a cam arm extension of said toggle-link mechanism. In this second embodiment the rockable stop member 30 is slightly different in shape, being more like a bell crank in action.

, By using the spring urged toggle-link mechanism as shown in Fig. 3 considerable downward pressure is exerted upon the rockable measuring element 30 thereby insuring the return of said measuring element 30 to its normal position during each cycle of the machine. The strong downward pressure upon member 30 would be too strong to be overcome by the sensing pin spring of the 12 stop in a condition where both the 12 stop and another stop were to be elevated. To overcome this difficulty a stud 8 is fixed in the interpreter plate in such a way as to engage and rock the toggle member 9 and thereby draw the toggle-link I!) out of engagement with the rockable measuring element 3. As may be seen in Fig. 3 the member 3 is now free to be actuated by the 12 stop. This inefiective condition of the toggle-link mechanism occurs only when the universal bar H (Fig. 2) has drawn all the reciprocating measuring elements 4 to their rearmost positions at which time a card is sensed and the sensings are transposed to the stops 1.

While there are above described but two embodiments of the invention, it is possible to produce still other embodiments without departure from the inventive concept above disclosed, and it is, therefore, desired that only such limitations shall be imposed on the appended claims as are stated therein, or required by the prior art.

What I claim as new and desire to secure by Letters Patent, is:
